Differing rates of fungi in sinonasal cultures from pediatric sinusitis patients.

Objectives: Pediatric chronic rhinosinusitis (PCRS) is a unique clinical entity and the underlying source of inflammation is unknown. Certain subgroups, such as children with nasal polyps and cystic fibrosis (CF) sinusitis are often recalcitrant to standard medical PCRS treatments that target bacterial inflammation. Fungal infection and allergy to fungal proteins drive inflammation in other airway diseases, resulting in chronic inflammation of both the upper and lower airways.

Can pediatric sleep questions be incorporated into a risk model to predict respiratory complications following adenotonsillectomy?

Background: Adenotonsillectomy, one of the most frequent surgical procedures in children, is usually performed for sleep-disordered breathing, a disease spectrum from primary snoring to obstructive sleep apnea. Children undergoing an adenotonsillectomy may be at risk for perioperative respiratory complications, necessitating intervention or escalation of care. However, there is no effective preoperative screening or risk-stratification model for perioperative respiratory complications that incorporates not only clinical history and physical examination but also sleep question responses for children as there is for adults.

MicroRNA Microarray Profiling in Infantile Hemangiomas.

MicroRNAs are short, noncoding RNA molecules that negatively regulate the stability and translational efficiency of target mRNAs. They are critical regulators of growth and development. Our aim was to identify microRNAs involved in the growth and regulation of infantile hemangiomas.

Tracheal Cartilaginous Sleeve in Syndromic Craniosynostosis: An Underrecognized Source of Significant Morbidity and Mortality.

Tracheal cartilaginous sleeve (TCS) is a rare and previously unrecognized source of morbidity and mortality in patients with certain craniosynostosis syndromes. There is a paucity of reporting on this airway anomaly, and the true incidence of TCS is largely unknown. The purpose of this study was to investigate the incidence of TCS among patients with syndromic craniosynostosis at our institution.

Pediatric lymphedema caused by diffuse cervical lymphadenopathy: A case report and review of the literature.

Pediatric head and neck lymphedema is rare and there have not been any reported cases in children. Here we discuss severe, diffuse head and neck lymphedema in a child caused by compression of the internal jugular veins by lymphadenopathy from Kawasaki's disease. With steroid and intravenous immunoglobulin treatment, the lymphadenopathy improved and facial edema slowly resolved.

Resistance to thyroid hormone associated with a novel mutation of the thyroid β receptor gene in a four-year-old female.

Resistance to thyroid hormone (RTH) is a rare syndrome of reduced responsiveness of target tissues to thyroid hormone and is caused mutation in the thyroid β receptor gene. We report a novel mutation, E445X, causing RTH in a 4-year old girl. The patient exhibited extreme signs and symptoms of RTH at an early age, and had a large compressive goiter.

Case report: Treatment failure using propanolol for treatment of focal subglottic hemangioma.

Subglottic hemangioma is a rare, potentially life threatening tumor of infancy which poses serious treatment challenges. A number of medical and surgical therapies over the years have met with variable success, and are associated with numerous potential morbidities. A potential windfall in the management of infantile hemangiomas has arisen with the recent identification of propanolol as a highly efficacious and relatively safe new treatment modality.
